22 Claims. (Cl. 141-9) This invention relates to washing machines.

One of the principal objects of the invention is the provision of awashing machine of simple and compact construction, in which thearticles to be washed may be readily inserted within and withdrawn fromthe machine.

Another object of the invention is the provision of a washing machinehaving a casing, and a movable cover member which is adapted toefiectlvely retain the washing fluid within the easing during operation,and is adapted to be read- 11y moved to an open position substantiallywithin the horizontal confines of the casing to permit access thereto.

Another object of the invention is the provision of a washing machine ofthis character having simple and effective means for supporting racks orother articles within the casing while permitting the cover to be movedwithin the casing to positions beneath the rack supporting means.

Another object of the invention is to provide a washing machine of thischaracter having a pivoted cover adapted to be readily rocked topositions permitting access to either of opposite sides of the casing.

Other objects and advantages of the invention will be apparent from thefollowing description, the accompanying drawings and the appendedclaims.

Fig. 7 is a sectional view of the trunnion as indicated at of Flg. 2.

A washing machine of approved construction embodying the invention hasan open-top tank containing washing mechanism and a support for thearticles to be washed whose supporting surface is located on the levelwith the upper edge of the tank. Above the tank is supported anopen-bottom casing providing a chamber in which the articles to be actedupon by this washing mechanism are placed. To permit access to the 5washing chamber, this casing is so supported that it maybe tilted tobring one of its edges well above the top of the tank, while, at thesame time, the opposite edge of the casing moves downwardly into thetank so that the center of gravity of the whole casing is only slightlyraised. It is, therefore, possible to tilt the casing with littleefiort, and no counter-balancing means are required.

To permit one edge of the casing to move down into the tank, I mount thesupport for the articles ence designate like parts throughout theseveral views thereof, illustrate in Figs. 1, 2 and 3 a washing machineof this character having an open top tank structure In suitablysupported upon legs I I and having a. movable casing or cover member I!which serves as a closure for the open top tank I and, when in closedposition, cooperates therewith to provide an enclosed washingcompartment. Rack supporting tracks I l are provided within the tank,preferably at about the plane of the top edge ii, for the reception oftrays or racks or similar containers for articles to be washed. Suitablewashing heads are provided which are adapted to spray fluid jets uponthe articles to be washed and, as shown, include a rotary wash arm 20and rinse jets, one of which is shown at 2|. The rotary wash armconsists of a hollow member provided with radial arms having nozzles,some or all of which may be inclined so as to cause rotation of the washarm by the reaction force of water discharged from the nozzles.

The tank I0 comprises vertically extending end walls 22 and side walls22', and an inclined bot- 50 tom wall 23 so shaped as to direct theliquid contents of the tank into a sump 24 which may be formed as anintegral part of the tank II. At the junction of the sump 24 and tank I09. suitable supporting ledge 25 is provided for the reception of aremovable strainer 26 having a perforate bottom member 21 for thecollection of solid material dislodged during the washing operation. Asuitable drain, such as the threaded outlet 23, is provided to which apipe connection may be attached for draining away the washing or rinsingliquid. As shown, a stand pipe 30 is provided at the outlet 28 so that aproper level of washing liquid may be maintained in the sump 24 duringwashing operation. The stand pipe 80 is provided with a tapered end 3|snugly received within a tapered socket formed in the bottom wall of asump 24 immediately above the threaded portion 28 for the readyattachment and detachment of pipe 30 and to provide a watertight jointto prevent the unintentional escape of washing liquid. The stand pipe3|) is provided at its upper end with an opening or overflow outletthrough which water, grease, scum, and the like, may pass upon exceedingthe predetermined desired level within the sump 24. The pipe 30 isformed with a baille 32 spaced above the overflow outlet and providing ahandle for the pipe.

A circulating pump 33 having suitable driving means, such as the motor34, is provided for the circulation of washing liquid and actuation ofthe wash arm 20. As shown, one side of the tank structure ill oppositesump 2i is left open, and the motor 34 and pump 33 are mounted withinthis space so that access is readily had thereto, the motor beingsupported upon a shelf 35 carried by the tank I and legs H. The pump 33is provided with a suction inlet 36 extending through an opening in theside wall of sump 24 into lower portion of the sump 24 through which,during actuation of the pump 33, washing liquid will be drawn fordischarge through pump outlet 33. The suction inlet is formed with anattaching flange 36 adapted to be bolted in liquid tight relation aboutthe opening through the sump wall. The upper portion of pump outlet 38is flanged as indicated at 38' for attachment to the flanged end 39' ofa pipe 39 extending through an opening in the lower inclined wall 23 ofthe washing compartment of the tank Ill. Preferably bolts pass throughflanges 33 and 33' and into a shouldered portion of wall 23 to close theopening through which pipe 39 passes. Mounted in pipe 39 and held inplace by nut II is a rod 42 providing a bearing for supporting the washarm 2|). The upper end of pipe 39 communicates with a central opening inthe rotary wash arm to provide passages for the flow of water from pipe38 to the wash arm 20. During operation of the device, water iscirculated by the pump from the sump to the wash arm where it isdischarged at high velocity against the articles to be washed, drainsfrom the tank into the sump, and is again recirculated by the pump.

The rinse arm 2| is preferably of rotary type generally similar to thewash arm 20 and, as shown, is pivotally supported at 43 from a pipestructure 44 which may be connected to a suitable source of supply ofrinsing water.

To permit easy handling of the articles to be washed they are preferablyplaced within the machine in suitable racks such as illustrated at 45;these racks being of such size as to be readily received upon the trackstructure it of the washing machine. Suitable rack supporting tables orshelves shown at 4B are shown provided at substantially the level of thetrack structure so that the article carrying racks 45 may be movedeasily, and without lifting, into and out of the washing machine.Suitable connecting brackets 41 may be provided, as shown, forsupporting the tables 45 from the tank structure Ill. As shown, thetrack structure ll comprises rack supporting rails 50 which arepreferably of angular cross section having horizontally extendingportions for the support of the racks or trays and upstanding portions52 for the guidance of the racks. Suitable supporting means are providedfor the track structure and are shown as vertically extending arms oruprights 54 suitably attached to the track members 50, as by means ofrivets 55, and supported at their opposite ends 58 within projections 51which are preferably formed integrally within the tank structure Ill.The projections 51 are preferably of socket like form within which theportions 56 may be securely held for the support of the track structureI, and from which they may be readily withdrawn when it is desired toremove the structure ll from the machine, as for the purpose of cleaningit. The vertical supports 54, which are attached to the track structurenear the middle of its sides. are offset, as shown more clearly in Fig.3, from the side walls of the tank a suflicient distance to permit thesides of the tilting casing to enter between them and the side walls ofthe tank. At the same time, these supports 54 are near enough the sidesof the tank to clear the wash arm. The rails 5|! of the structure it areshown shorter in length than the width of the tank in so that aclearance space is provided between the ends of the members 50 and theupstanding walls of the tank for the passage of the cover member l2 ofwhich a portion is adapted to be received within the tank when it ismoved to open position. The vertically extending portion of the rinsepipe 44 is preferably arranged at the side of the tank intermediate thevertical planes passing through the spaced trunnion axes. This pipe asshown is within and adjacent the side wall of the cover member, and.passes upwardly between the cover and the side rail 50.

The cover member I2 is preferably of approximate semi-cylindrical formand is shown substantially semicircular in cross section. The curvedshell or circumferential portion Gil is provided with parallellyextending end portions iil which merge gradually into the curved portion60 to provide a structure of sufllcient depth within the limitedconfines of the radius of the member 60. The cover structure iscompleted by parallel side walls 52. The shape of the cover member I2 isproportioned to serve as a deflecting surface so that jets of wash waterstriking the cover will be directed back against the articles beingwashed. Spaced sets of trunnions 53 are carried by the opposite sidewalls 62. The trunnions provide parallel axes which are preferablyspaced an equal distance on opposite sides of a vertical plane extendinglongitudinally through the center line of the cover l2 and providepivotal supports upon which the cover member l2 may be rotated toprovide an opening at either of opposite ends of the machine. The covermember i2 is supported above the tank Ill by means of suitable bearingbrackets 64 which are mounted on the tank l0. As shown, the brackets 64comprise yokelike bearing seats 65 within which the trunnions may bereceived; the bearing seats being open outwardly and inwardly so that asthe casing i2 is moved the one pair oi. trunnions 53 may rotate in thecorresponding bearing seats 55 while the opposite pair of trunnions maymove upwardly in a curved path without interference from the supportingseats.

The cover mounting is such as to permit free cover movement without theobjectionable noise of metal to metal impact upon closure. As shown.

particularly in Fig. 'l, a trunnion 83 is constructed as a cylindricalstud IN] having an end flange III which is fixed to the cover side wall52. Rotatably mounted on the stud H0 is a metal sleeve H2 which has onits outer surface a yielding material such as an encircling band ofrubber H3. The rotatable part is held in place on the stud by provisionof a washer ill that is attached to the stud end by a screw iii. Thewasher is preferably somewhat smaller in diameter than the rubber bandand, as shown, is substantially the same diameter as the metal sleeve.Free rotation is afforded by movement of the trunnion stud on the metalsleeve, and freedom from the noise of metal to metal impact upon closureof the cover is provided by engagement of the yielding rubber band withthe trunnion support or bracket 84.

The cover I! is provided with suitable handles or grips Gil by which itmay be moved. The handles 88, positioned at opposite ends of the casingportion Bil, are provided with lugs 69 which, in open position of thecover member l2, areadapted to engage the lip ii of the tank Ill tolimit the movement of the cover member. The edges of the tank and theedges of the cover member which are parallel to the tilting axis of thecover member are termed herein for purposes of description the "ends ofthese respective parts, and the edges of the tank and cover member whichare perpendicular to the tilting axis are termed the "sides"; but it isto be understood that this implies no limitation as to the dimensions orshape of these parts. The trunnions 83 are positioned so that as thecover member is moved to open position, the balance of weight, or centerof gravity, of the cover member will be shifted to a position to theoutside of the supporting trunnions 63 to maintain the cover member inopen position.

Suitable limiting means are incorporated in the open ends of the bearingseats 85 to prevent movement of the cover I! beyond the normal openpositions determined by the lugs 69. As shown, the limiting meanscomprise curved latching recesses 12 which extend from opposite sides ofthe trunnion supporting members 64 and are so positioned that as thecover l2 rocks about one pair of trunnions as a pivot the opposite pairmay move out of engagement with the bearing seats without resistance.Should the cover be thrown or pushed open with considerable force,

such as would tend to cause the trunnions 03'. to bodily move out oftheir bearing seats 85' about the point of engagement of the stop 88with tank III as a pivot, such movement beyond the normal open positionis restrained by engagement of the trunnions GI within their latchingrecesses 12. In closed position the downwardly extending edges of thecover member II, as designated by the numeral 13 for the end portions GIand the numeral II for the side walls 62, extend within the open top ofthe tank ID, as defined by the lip I5, an amount sufllcient to providean effective seal against the passage of washing fluid during operationof the machine even though the cover member does not actually contactwith the tank in. As shown, the end portions 22 adjacent the lip it areflared outwardly at 15 to receive the edges ll of the cover member. Theconfiguration or curvature of the surfaces 15 is such that any waterfrom the jets or splashed against the surfaces will be deflected intothe tank and will not pass through the clearance opening between theedges II-N and the lip 15. when the cover member is moved fromclosedposition to an open position, one of the ends 6| moves downwardly intothe tank l0 while the opposite end it moves upwardly to provide anopening approximately equal to the height of the washing chamber asdefined by the cover member in closed position. The end Iii that isreceived within the tank moves downwardly between the lip ii of the tankand the adjacent overhanging end of the track 50, passes under the pathof travel of the overhanging end of the wash arm 20, and comes to restwhen the lug 69 contacts with the lip ii; the degree of opening beinglimited to avoid contact with the supporting members 54 of the track.

By providing a cover member with parallel spaced trunnions, which permitthe cover member to open to either of opposite ends, articles to bewashed may be inserted within the machine at one end and, after washing,may be readily removed from the opposite end of the machine by merelyshifting the cover member l2. This arrangement of parts permits thewashing machine to be installed against a wall of a room and requiresfor its installation a space substantially equal to the horizontaldimensions of the tank structure since the cover member, in openposition, is received within the tank and stands substantially withinthe confines of the tank area. When it is desired to disassemble themachine, as for the purpose of cleaning it, the entire cover member I!may be easily removed by merely lifting the trunnions 83 out ofengagement with the yoke like supporting bearings 64. The trackstructure I! and the strainer 28 may then be lifted out. Removal of thestand pipe Mi permits the sump 24 to drain so that the entire interiorof the machine is then exposed and readily accessible.

Referring now to Figs. 4, 5 and 6, a machine is shown of a type which isadapted for use in restricted areas, such as when positioned with itsback to a wall or in a corner of a room so that the interior may bereached from only one end. The machine is provided with a cylindricalopen bottom casing or cover member Ill having an upper wall ofsubstantially semi-circular cross section comprising a curved surface Itand opposed parallel side walls 82 upon which are provided alignedtrunnions ll positioned to one side of a vertical plane extendingthrough the longitudinal center line of the cover 80. Suitable brackets86 are provided on the tank II for the pivotal support of the trunnionsII and to permit the cover to be moved from a closed position, in whichthe open top of the tank is enclosed, to a position providing an openingwhich is approximately equal to the height of the wash chamber asdefined by the cover member when in closed position. As shown, the upperportion of the tank IB' isprovided with a ledge II having a portionextending across the front end 22 of the tank, and continuing portions8! which extend along opposite sides 22' of the tank to points short ofthe vertical plane passing through the trunnion axis. The upper surfaceof this ledge is below the top edge of the tank, and the bottom edge I!of the cover in closed position lies just over the surface of the ledge,providing a substantially leak-proof construction about this portion ofthe tank and cover, and at the same time providing freedom of upwardopening movement of this part of the cover. The portions 8! of the ledgealong the sides of the tank terminate as shown at about the verticalplane of the trunnion axis, so that the rear end of the cover ispermitted to freely move down into the tank. To the rear of the verticalplane passing through the trunnion axis, the open edge of the tank I isprovided with an inturned flange which, in closed position of the covermember, is. engaged by an outwardly turned flange extension ll of thecover member. The inturned flange iii of the tank and the outturnedflange H of the cover member extend across the rear edge of these partsand thence forwardly to approximately the vertical plane passing throughthe trunnion axis. The overlapping of flanges 10 and H provides aneflective seal between the tank and cover member to restrain the passageof washing liquid at this portion of the respective parts. A suitablehandle 93 is provided on the cover member for convenience in moving thecover member. The trunnions 84 are so positioned and the curvature ofthe cover member portion Bi is so proportioned that as the cover memberis moved to open position the balance of weight or center of gravitywill move to a position beyond the trunnion pivot point so that thecover member will be maintained in open position and will be held insuch position by engagement of the surface of the portion Bi with theinner surface of dense III of the tank III.

A rack supporting track structure I4 is provided and, like the structureI4, is readily removable. As shown, the track structure ll comprisesparallel horizontally extending rails 90 having upturned flanges 9| forthe guidance of a rack 45 and is provided with a limiting rear flange 92which limits the insertion of a rack to a position substantially centralwithin the washing machine. The tracks 90 are preferably positioned at alevel about or slightly above the plane of the open edge of the tank illso that racks may be inserted or withdrawn without the necessity oflifting them over the edge of the tank. A suitable shelf extension 91may be attached to the tank structure of the machine and positioned atthe level of the tracks 90 to aid in the handling of the dish carryingracks. The track structure it is shown supported by means of spacedmembers ill that extend forwardly toward the front of the tank andterminate in end portions 95 that are telescopically received withinsuitable horizontal sockets 98 provided adjacent the ledge 88 at therack receiving side of the tank, and by laterally proiecting members 98that extend from the opposite sides of the track structure and terminatein end portions 99 that are received by a downward interfltting movementwithin sockets or grooves I00 formed in the upper faces of the ledgeportions 88'. The rack support is thus in the form of a cantileverhaving an overhanging rear end which permits free passage of theadjacent portion of the cover member down within the tank beneath thisoverhanging end of the support, and beneath the path of travel of theoverhanging end oi the wash arm. The side rails 80 of the racksupporting structure are spaced inwardly from the inner surface of theside walls or the tank so that the lower edges of the sides of the covermember fit within and between these rails and the side walls of the tankwhen the cover is in closed position. The track structure H may bereadily disengaged from mounted position by vertical withdrawal of themembers 08 from the supporting grooves I00 followed by a horizontalrearward movement of the structure I4 to disengage the members from thesockets 95. The vertically extending portion of the rinse pipe 44 ispreferably arranged as shown at the side of the tank adjacent thevertical plane of the trunnion axis. This pipe extends upwardly withinthe side wall of the cover member, passing between the cover member andthe side rail 80. The remaining parts of the washing machine aregenerally similar to corresponding parts described for Figs. 1, 2 and 3.

There is thus provided a washing machine of compact construction havingan easily accessible washing compartment, and which is adapted forinstallation in positions, such as against a wall, which permitsefllcient utilization of kitchen space. The cover member of the machineis so arranged that it may be opened to a position substantially equalto the height of the wash chamber, and is maintained in such position byits own weight while standing substantially within the floor area of themachine. Articles to be washed may readily be inserted within andwithdrawn from the machine on an easily removable track structure whichis so positioned as to avoid interference with the cover member which,in open position, is adapted to be received within the cas ing. Simpleand effective means are provided for retaining the washing fluid withinthe machine during operation. A construction is provided which permitsthe machine to be readily disassembled for cleaning.
